Differential is a low RPM under-achievement at 3.73:1, there's no burning tires in first gear. On shift it can chirp, that's it. But loves the highway, it just wants to fly. That's what I've always liked about it. No matter how steep a hill it gains speed under little acceleration, and without more.

A big block with 3.73s should be melting tires. What's wrong with yours?
